windows and more-particularly to means for mounting a storm window on a window opening. i 1 J .The principal object ofthe invention is the provision of a storm window and mounting frame. 1

Av further object of the invention .is the provision of a simple and inexpensive means for positioning a storm window in desirable location on a Window opening.

A. still further object of th invention isthe provision of a storm window and mounting frame having locking means formed thereon for interengagement.

- Th storm window and mounting frame shown and described herein comprises an improvement in the art of mounting storm windows on window openings and particularly dwelling house window openings. It is well known that many and various types of storm windows are commonly appli-ed'towindow" openings for the insulating effect obtainedtherefrom@ It is also well known'that many and various methodshave'been-proposed window assemblies on the window openings.

The present invention relates to a storm window having a lip type fram provided with a plurality of longitudinally extending grooves formed therein and a mounting frame comprislng a the lip frame of the storm window and having a plurality of longitudinally extending ribs formed therein for registry with the said grooves in the said storm window frame, The storm window mounting frame is adapted to be time of installation so as to cause a plurality of ribs therein to register with the plurality of grooves in the storm window frame and thereby lock the same in desired relation on which the storm window and mounting frame is positioned.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a front plan View of the storm window and mounting frame.

bifurcated member slidably engageable on 4 Claims. (01. 20-55) distorted at its ,Land defines a window opening as,

2 Figure 2 is a vertical cross section taken on line 2-2 of Figure 1.

Figure 3 is a vertical cross section in enlarged detail taken on line 33 of Figure 1.

Figure 4 is a vertical cross section in enlarged detail taken on line 4-4 of Figure 1.

Figure 5' is a cross sectional View, substantially as taken along the lineIII- III of Figure 1, with the frame member in theundistorted position before engagement with the frame flange.

-By referring to the drawings and Figures v1 and 2 in particular it will be seen that a window has been disclosed for example, A storm window compriscasing l0 including a sill II in a dwelling house.

-in a main frame l2 having a pair of sash l3 and I l positioned thereinis disposed in the opening defined by the window casing I0 and is secured in the: said opening in the casing H] by a mounting frame l5. The mounting frame l5, as

may best be seen by referring to Figures 2, 3 and 4 of the drawings, comprises abifurcated member defining a deep channel in which an out- .wardlyextending flange iii of the main frame I2 may be engaged. The mounting frame I5 is identical in cross section, in the vertical side sections and the horizontal top section thereof and differs slightly in the lower horizontal section thereof which is modified for engagement with the sill l l heretofore referred to.

In FiguresfZ and 4 of the drawings the modified sill engaging portion of the fram may be seen and is indicated by the numeral IT. The modified sill engaging portion I1 is provided with an outwardly extending flange I8 through which a plurality of screws l9 may be driven so as to mount the same in upright position on the sill II as shown.

By referring to Figures 2 and 3 of the drawings it will be seen that the vertical side sections and the upper horizontal section of the mounting frame l5 are provided with registering ribs and grooves 20 and 2|, respectively, the ribs 20 being formed on the mounting frame i5 and the grooves 2! being formed in the flange I6 of the mounting frame 12. It will be observed that a plurality of screws 22 are positioned through the mounting frame l5 so that when they are engaged in the casing If! they serve to move the bifurcated members of the mounting frame 15 toward one another and hence bring the ribs 20 into positive registry with the grooves 2! heretofore described. 7

It will thus be seen that the storm window and mounting frame as disclosed herein may be mounted on the window casing ID in any desired position with respect to the window opening defined by the window casing II] by simply engaging the flange it of the mounting frame l2 of the storm window in the bifurcated mounting frame members l5-i5 and then securing the mounting frame member |5!5 to the casing as by the screws 22. It will be obvious that this method of mounting the storm window on the dwelling house wvindow casing to eliminates the need of blocking up the same as has hertofore been customary, as the mounting frame l carries the storm window by reason of the interengagement of the ribs and grooves r20 and;-2:l,:re-

spectively. The storm window frame !2 is, in

effect, hung from the horizontal top member i5 of the mounting frame and secured againstsideward movement on the dwelling house window casing l6 by reason of its engagementwviththe vertical standing members |5l5. The modified sill engaging portion i? slidably engages the lower horizontal section of the flange: I 5 formed on the storm window fram i2 andprovidesthe necessary build up to compensate for the drop sill construction common indwelling house window constructions.

'It-will thus be'seen that asimple and efiicient storm window and mounting frame therefor has been disclosed which provides positive interengagement between the storm window frame and the mounting frame and thereby secures the stormwindow in desired'relation on the window opening.

Having thus described my invention, what I claim is:

1. Thecombination ofa storm window including a main frame havinga flange, a pluralityof grooves formed longitudinally in said flange and said frame.

2. A' storm window including-a 'main frame -a lip type storm window comprising a bifurcated rm'emberqh'avingl a plurality of longitudinally extending ribs formed on the inner surface of one '"ofthe bifurcations thereof, and a storm window rframe having a plurality of longitudinally extending ribs thereon; and means for mounting "the-said mounting frame on a window casing for distorting the same so as to engage the ribs of the mounting frame in thergrooves ofi the storm window 1 frame when the same is positioned .;-in

the bifurcated frame.

'4. The combination of a storm windowiframe having a lip type' flange :and :a mounting frame therefor comprising a bifurcated memberlengaging the lip type flange, the saidlip :type ffla'nge and the bifurcated'member both.having irregular surface patterns for registrywith one: another so as to secure the said storm window frame against movement in :the'said mounting frame.
